<p>权限是对特定资源的访问许可，所谓权限控制，也就是确保用户只能访问到被分配的资源</p> <p>而前端权限归根结底是请求的发起权，请求的发起可能有下面两种形式触发</p> <ul><li>页面加载触发</li> <li>页面上的按钮点击触发</li></ul> <p>总的来说，所有的请求发起都触发自前端路由或视图</p> <p>所以我们可以从这两方面入手，对触发权限的源头进行控制，最终要实现的目标是：</p> <ul><li><p>路由方面，用户登录后只能看到自己有权访问的导航菜单，也只能访问自己有权访问的路由地址，否则将跳转 <code>4xx</code> 提示页</p></li> <li><p>视图方面，用户只能看到自己有权浏览的内容和有权操作的控件</p></li> <li><p>最后再加上请求控制作为最后一道防线，路由可能配置失误，按钮可能忘了加权限，这种时候请求控制可以用来兜底，越权请求将在前端被拦截</p></li></ul> <h2 id="二、如何做"><a href="#二、如何做" class="header-anchor">#</a> 二、如何做</h2> <p>前端权限控制可以分为四个方面：</p> <ul><li>接口权限</li>
